【摘要】 为探明“尼托温-2000”对蚕茧产量及生命力的影响,在中秋蚕期进行了添食试验。按不同的浓度、添食次数、龄期采用正交试验设计。结果表明,二、三龄期添食“尼托温-2000”对提高蚕茧产量有一定作用,高浓度少次添食、或低浓度多次添食效果明显;添食对蚕的生命力的影响不显著。更多还原

【Abstract】 To investigates the influence of Nituowen-2000on cocoon output and viability of silk-worm,the experiment was designed with orthogonal in the mid-autumn rearing season in2001.The experimnet was made by different density,feeding,and different instar.The result showed that feeding Nituowen-2000has positive effect.There is significant effect feeding in second and third instar of lar-va than that of other instar,and feeding in high density is also better than that of low density.The in-fluence to viability of silkworm is also better than that of low density.The in fluence to viability of silkworm is no significant.更多还原
